Formation of Aluminosilicate Glasses Containing Rare‐Earth Oxides

Abstract

Formation of aluminosilicate glasses containing oxides of rare‐earth elements, e.g. Sc, Ce, Pr, Nd, Eu, Gd, Tb, Dy, Ho, Er, and Yb, was studied by melting at 1550°C and air quenching. The upper limit of the amount of rare‐earth oxide which can be incorporated into the aluminosilicate glasses decreases according to the lanthanide contraction.
